ABSTRACT Research question This study aims to address the limitations of current typologies and determinants of innovation by proposing a three-dimensional (3D) conceptual innovation model, in which three dimensions (i.e. ‘form’, ‘nature’ and ‘goal’) are related to each other, resulting in eight innovation types. Based on this model, this study first examines the extent to which voluntary sports clubs (VSCs), sports federations (SFs) and local sports authorities (LSAs) implement the innovation types differently. Second, the effects of managerial, organisational and environmental determinants on the eight innovation types are investigated. Research methods Online questionnaires were distributed to VSCs, SFs and LSAs. Key representatives were asked to describe and categorise each innovation that their organisation had implemented in the previous four years. In addition, they were asked for their opinion on management, structural organisational characteristics and environmental influences. Results and Findings Findings show that there are significant differences in the extent to which the eight innovation types are implemented by SFs, LSAs and VSCs. Also, the assumption that different innovation types relate to one or more managerial, organisational and environmental determinants is confirmed by logistic regression analyses. Implications As such, this study's model can serve as an extensive framework to identify innovation types in and outside a sporting context. Furthermore, the findings provide (sports) policymakers with insights into the innovativeness of (sports) organisations and how they can support it.
